Resistance probes for the laboratory can be divided into two main categories: (1) those involving direct use of resistance; and (2) those involving an indirect use of resistance. Described are several applications of both types related to chemistry and physics. (RH)

Describes two complementary laboratory exercises that use the glass fiber assay to assess receptor specificity and hormone binding affinity in rat liver cytoplasmic extracts. Details the methods, materials and protocol of the experiments. Discusses the basic concepts illustrated and the feasibility of using the experiments at the undergraduate…

Describes an experiment to discover the topology of plasma membrane aminophospholipids (phosphatidylethanolamine and phosphatidylserine) using whole platelets and trinitrobenzene sulfonate (TNBS) as a probe. Reports changes in phospholipid distribution during platelet activation with simultaneous action of thrombia and collagen. Details the…

Suggesting that learning be considered as a generative process, attempts to: (1) place generative learning ideas in the context of other viewpoints of learning; (2) explicate key postulates of the generative learning model; and (3) examine implications of these theoretical ideas for teaching, learning, curriculum development, and research. (JN)

Describes a survey which was designed to obtain information on acid rain education. Reviews results pertaining to instructional time, instructional topics, use of labs from a common resource guide, and preference of materials related to acid rain education. (ML)

Reports results of an investigation of science content of 10 recently published elementary science textbook series. Results show that though textbooks cover a wide range of science content, they do not promote or encourage the development of scientific thinking or attitudes, nor do they engage students in applying cognitive processes that are…

Provides highlights of lectures, workshops, papers, and symposia presented at a conference which addressed such areas of chemical education as college/high school chemistry teaching; curriculum/curriculum development; safety; two-year programs; computers; toxicology and health hazards; problem-solving; writing skills development; textbooks;…

Nuclear arms education is being addressed in many academic disciplines and can be approached from many viewpoints. Rationale, ethical issues, instructional strategies, European views, and course materials are considered. A syllabus and references are also included for a course titled "Physics of Nuclear Arms and Nuclear War." (DH)

Outlines and discusses elements for designing elementary school science programs, considering: goals and objectives; scope; sequence (arrangement dependent on logic, topic, hierarchy, developmental psychology, or combinations); instructional strategies; evaluation; and inservice education. Also suggests that textbooks serve as points to begin the…

Reports how a school district's elementary science curricula and in-service programs were improved through a series of minicourses. Appraises the procedure, components, and requirements of this approach. Also describes the science loan kit program that was implemented to facilitate hands-on instruction. (ML)

Describes an innovative freshman chemistry program in which course sequences have been designed to accommodate students with strong or weak chemistry backgrounds or with no previous chemistry at all. Includes information on courses offered, instructional strategies, and laboratory examinations. (JN)

Describes the development and rationale of a hands-on, process-oriented elementary science curriculum that emphasizes decision making, problem solving, current issues, and the human element in science and technology. (JHZ)

Presents varying philosophies of science education based on educational ideologies and images of science. Redefines science as a problematic human activity that has the potential to develop an informed and effective citizenry. (ML)

Describes the science program at Incarnate Word, a private Catholic girls' college preparatory school in San Antonio (Texas). Focuses on the chemistry curriculum and the instructional strategies/materials (such as learning activity packets) used in the curriculum. (JN)

Describes the new primary and secondary-level science curriculum in Sierra Leone as well as new teacher roles and instructional approaches. Indicates that curricular changes in this country should address needs related to job opportunities, the environment, and citizenship. Results of 1972-80 secondary-level biology, chemistry, and physics…
